<h3><a class="toc-backref" href="#id18" role="doc-backlink">3.22.3</a><a class="headerlink" href="#id3" title="Link to this heading">¶</a></h3>

as CMake 3.21 and below did.  This bug was fixed in 3.22.0, but exposed
errors in existing projects.  The fix has been reverted to restore
compatibility.  The fix may be restored in a future version of CMake
via a policy.</p></li>
